Such a connection for building elements is e.g. known from French Specification 1.289.484, FIG. 7. In order to obtain the known connection it is necessary to use external metal coverplates in order to prevent sliding movements between said joining faces f.i. during glueing of the connection. As a matter of fact the use of such coverplates means a complication when assembling the parts to be interconnected. Further it is necessary to use grooves in the outer faces of the building panels for locking the edges of the cover plates. The object of the invention consists in the removal of said disadvantages, obtaining at the same time new advantages.

The connection for building elements according to the invention is characterised by complementary interlocking end-profiles along said edges of the coverplates of adjoining panels, each end profile forming part of a panel. In the first place the advantage of a simplified assembling of the building elements is obtained. A further advantage consists in a complete thermal insulation of the connection. The glue connection shows a favourable matching and a self centring action, and is only stressed by shearing forces. Without any difficulty a real hermetically sealing may be obtained.

An efficient embodiment of the invention is characterised in that in transverse section of the connection the edges of the slanting joining face of a first panel are provided with transverse elongations for enclosing the end profile of the other panel.

In many cases it is desirable to have rounded off edges at the exterior of a right angled panel connection. This may be obtained by application according to the invention by transverse elongations of the outer coverplates of two adjoining panels, showing the configuration of cylinders with a common axis, coinciding with the inner edges. of the slanting joining faces.

The connection for building elements according to the invention is very suitable for making trihedral connections, which may be obtained by combining two right angled connections according to the invention. For obtaining such trihedral connections according to the invention it is possible to apply straight saw cuts.

The invention covers further a method for making panels or building elements for the above connections. This method is characterised in that each time two complementary end profiles are obtained from a single box' profile, said box profile being divided into two complementary end profiles by sawing or a similar treatemnt along a plane, parallel to the longitudinal directon of the box profile. By starting from a single box profile it is possible to obtain without difficulties complementary end profiles withexcellent matching properties, enabling an easy assemblying of the connection.

The invention will be further explained by means of the embodiments of the drawings.

FIG. 1 gives a transverse section of a single basic box profile for obtaining two complementary profiles according to the imvention.

tion of FIG. 3.

FIG. 1 gives the shape in transverse section of a single box profile, especially manufactured from glass fibrepolyester resin, said profile being divided into sections of suitable length, whereupon the sections are divided into two complementary parts 1 and 2 by a longitudinal saw cut 3. This saw cut is directed in a plane parallel to the longitudinal direction of the profile in such a way, that two complementary end profiles are obtained. The end profiles l and 2 are respectively connected to .the edges of two building elements or panels 4 and 5, each panel being build up out of flat cover plates 6, 7, 8 and 9. The coverplates are fastened to the end profiles by glueing, rivetting or in any other suitable way. The hollow panels thus obtained may be provided with a filling, e.g. having a cellular structure, a

honey comb structure or consisting of foam plastic.'

Further particulars about such building elements belong to the prior art and are e.g. specified in the abovementioned French specification.

For obtaining a rigid connection between adjoining panels interengaging surfaces are covered by glue, whereupon the complementary end profiles are brought fully into contact with each other. After hardening of the glue a very strong connection is obtained, providing a hermetic sealing between the interior and the exterior of the panels.'

The connection according to the invention enables the use of straight saw cuts.
